NUT-WRENCH.

SPECIFICATION forming part of Letters Patent No. 626,228, dated June l6, 1899.

Applicatiun filed August 24, 1898. Serial No. 689,444. (No model.)

To all whom, it may concern:

Be it known that I, MILTON O. GOODPAS- TURE, a citizen of the United States, residing at Celina, in the county of Clay and State of Tennessee, have invented a new and useful Nut-Wrench, of which the following is a specication.

This invention relates generally to nut-- wrenches, and particularly to that class thereof known as sliding-jaw nut wrenches, the object of my invention being to provide a Wrench of this class which shall be cheap and simple in construction and in which the sliding jaw can be quickly and easily adj usted and secured without the use of the worm-screw or paw] and ratchet now in common use.

IVith these objects in view my invention consists, essentially, of a xed jaw having a shank provided with a series of serrations or indentations and a sliding jawhaving one or more corresponding serrations or indentations, said sliding jaw carrying one or more levers provided with one ormore locking-lugs adapted to enter the serrations or indentations between the xed and slidingjaws and hold them securely in their adj usted positions.

The invention consists also in certain details of construction and novelties of combination, all of which will be fully described hereinafter and pointed out in the claims.

In the drawings forming part of this speciiication, Figure l is a perspectiveview of a wrench constructed in accordance with my invention. Fig. 2 is a verticallongitudinal section. Fig. 3 is a top plan View. Fig. 4 isa detail View of one of the locking-levers.

In constructing a wrench in accordance with my invention I employ a fixed jaw A, which is attached to the shank B in the usual manner, and this shank is secured inthe handle C in any approved manner. The upper face of the shank B is provided or constructed with a series of transverse indentations or serrations D, preferably V-shaped in crosssection. The sliding jaw E is constructed substantially the same as the sliding jaw in an ordinary monkey-wrench, and comprises the front and rear rectangular-shaped'collar portions E and the connecting or shank portions E2, the lower or inner faces of said connecting or shank portion having one or more series of indentations which in size and vto mate or register.

shape correspond with those in the shank of the fixed jaw and with which they are adapted Locking-levers F are pivotally connected to the sliding jaw, preferably by means of a perforated ear F, which is adapted to enter a socket in the sliding jaw and through which a pivot-pin F2 is adapted to pass. Inwardly-projecting lugs G are carried upon the forward end of the levers F, which lugs are shaped to enter the recess or openings produced by the registering of the serrations or indentations in the Shanks of the fixed and slidingjaws,said lugs occupying the entire space and preventing any longitudinal movement of the sliding jaw. The rear ends of the levers areenlarged, as shown at F?, and carry a pin F4 upon their inner faces, the purpose of said pin beingto center a lcoil-spring II, which is interposed between the rear portion of the lever and the rearportion of the sliding jaw. v

In operation whenever it is desired to slide the jaw back or forth the handle portions of the lever are pressed inwardly by the thumb and foreii nger, thereby withdrawing the locking-lugs from the recess, and the jaw can then be slid freely upon the shank of the xed jaw until the desired adjustment is had,

.and the levers are then released and the springs will immediately project the lockinglugs carried by the levers into the recess or openings, and thereby securely lock the sliding jaw in its adjusted position.

It will thus be seen that I provide an extremely cheap and simple form of nut-Wrench which will successfully perform all of the objects for which it is intended.

Having thus fully described my invention,

Letters Patent of the United States, is

l. In a wrench of the kind described, the combination with the fixed jaw andvshank, of the movable jaw and shank, said Shanks having transverse indentations or serrations, and the levers pivoted upon the` sliding jaw and carrying lugs adapted to engage the indentations, substantially as shown and described.

2. In a wrench of the kind described, the combination with the fixed jaw and shank, of the sliding jaw and shank,'said Shanks having transverse indentations orserrations,"and the spring-actuated levers carried by the slidwhat I claim as new, and desire to secure by IOO ing jaw and shank and provided With'lugs at .their ends adapted to enter theindeniations or serrations, substantially as shown and described.

In 'a Wrench of the kind described, the

combination with the xed and sliding jaws and Shanks, said Shanks vhaxv'ing transverse serrations or indentations adapted to register l or mate with one' another, the levers pivotally connected with the sliding jaw or shank,

the lugs carried upon forward ends of said levers, and the springs interposed between the rear ends of said leyers and the sliding,` jew or shank, substantially as shown and described.
